Here are some English mnemonics related to chemistry.

General

The elements Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, and Bromine are always found as diatomic molecules:

  • Hydrogen Oxygen Nitrogen HALogens (group 7) - HONHAL
  • HNFOIClBr
  • HONClFIBr (say HONKLE-fibber)
  • HONClBrIF (say HONKLE-brif)
  • BrINClHOF (say Brinckle-hoff)
  • Old Henry's Nose Flows Clear Brown Ink
  • Have No Fear Of Ice Cold Beer
  • Never Have Fear Of Ice Cold Beer
  • I Have No Bright Or Clever Friends
  • I Bring Clay For Our New House
  • ClIF H Bron
  • HOFBrINCl Twins (twins because they exist in pairs)
  • There are seven such elements. The first one is the first element Hydrogen; the rest form a 7 on the periodic table: N, O, F across, then going down Cl, Br, I.

Oxidation and reduction

Acronyms for oxidation and reduction:

  • Oxidation Is Losing Electrons, Reduction Is Gaining Electrons: OIL RIG
  • Electron Loss Means Oxidation: ELMO
  • Losing Electrons Oxidation, Gaining Electrons Reduction: LEO the lion. GER! or LEO says GER

Oxidation and reduction in the electrodes of an electrochemical cell:

  • Oxidation takes place at the anode (both start with vowels) reduction takes place at the cathode (both start with consonants).
  • REDuction at CAThode: RED CAT
  • ANode for OXidation: AN OX
  • Anode for Oxidation: Adults Only
  • Reduction at Cathode: Roman Catholic
  • At the AN'ode Oxidation Is Loss; and Reduction Is Gain at the CAThoed: AN OIL RIG CAT

The elements that form hydrogen bonds when bonded to hydrogren are Fluorine Oxygen Nitrogen:

  • Hydrogen is FON! (fun)
  • I think about hydrogen bonds OFN (often)

Cations are positive, while anions are negative:

  • The letter t in cation looks like a positive plus sign +: ca+ion
  • Cations are pawsitive.
  • An ANION is A Negative ION.
  • Be POSITIVE about your CATs

Metals form cations in ionic reactions

  • Metal Cat, Metal Cat, Where is my Metal Cat?

Organic ions:

  • "A hot carbonium ion is a naked carbonium ion" -- George Olah, in lecture, 1966

The sequence of dicarboxilic acids is Oxalic, Malonic, Succinic, Glutaric, Adipic, Pimelic:

  • Oh My Stars, Green Apples
  • Oh My, Such Good Apple Pie

The list of elements from most electronegative to least electronegative begins Fluorine Oxygen Nitrogen Chlorine:

  • FONCl (phone call)
